Handheld Luminance Meter "BM-9A"

At the 28th Fine Tech Japan (LCD, Organic EL, Sensor Technology Exhibition) specialized technical seminar, I will also be giving a presentation. As μLED is becoming the mainstream device to meet the expanding display's color gamut and contrast, the uniformity of brightness and chromaticity has become an issue due to the intensification of self-emission. The world's first developed two-dimensional spectral radiance meter, SR-5000, can analyze subpixels smaller than 2um! In this presentation, I will introduce examples. ■ "Chromaticity and Uniformity Inspection in Micro LED" Presentation December 7 (Friday) 9:30–10:20 Optical Measurement Department Sales Group Manager Kazuto Nishikawa We sincerely look forward to your attendance!

We will be exhibiting the following products, including reference samples, at the "28th Fine Tech Japan" to be held at Makuhari Messe from December 5 (Wednesday) to December 7 (Friday), 2018, where we will propose measuring instruments and measurement methods. We also plan to showcase the SR-5000M measuring instrument, which can evaluate spectral variations within subpixels and spectral differences between pixels, essential for improving color accuracy in increasingly high-resolution displays. 【Overview】 Dates: December 5 (Wednesday) to December 7 (Friday), 10:00 AM to 6:00 PM (ends at 5:00 PM on the 7th) Venue: Makuhari Messe, Hall 2, Display Sensor Zone Booth: 11-6 <Main Exhibits> - 2D Spectroradiometer SR-5000 - Spectroradiometer SR Series - 2D Color Luminance Meter UA-200A - Spectral Illuminance Meter (Color Rendering Illuminance Meter) IM-1000 - Luminance Meter BM-9 / Illuminance Meter IM-600 / Illuminance Meter IM-2D / Ultraviolet Intensity Meter UVR-300 We sincerely look forward to your visit!

Topcon Technohouse Co., Ltd. has developed the "BM-9A," a successor to the handheld luminance meter "BM-9," significantly improving luminance accuracy and measurement range. Sales will begin in March 2014. The luminance measurement range has been expanded from the previous model's 0.01 to 19,990,000 cd/m² to 0.01 to 28,000,000 cd/m², and the luminance accuracy guarantee has been improved from ±4% to ±2%. As with the previous model, three types of measurement angle light receiving heads (2°, 1°, 0.2°) can be selected and exchanged. It also comes standard with USB communication and analog signal output functions, and a new zero correction function without a cap has been added, making it even more suitable for embedded applications as a "luminance sensor" in customer production processes and various industrial devices. By connecting an oscilloscope or similar device to the analog signal output, it is possible to measure response and flicker light. Additionally, it can be powered by AA batteries, allowing for the measurement of reflected luminance on floors and the luminance evaluation of guiding blocks for visually impaired individuals outdoors. Furthermore, measurement data collection via PC using the standard application software MT-100 is also possible.
